To (tZZ "1071 0771, it may concern.-

Be it known that I, TALBOT O. DEXTER, a citizen of the United States,and a resident of Pearl River, in the cou'nty'of Rockland, in the Stateof New York, have invented new and useful Improvements inPaper-Registerin g Instruments, of whichthefollowing,taken in connectionwith the accompanying draw ings, is a full, clear, and exactdescription.

The objects of my present invention are primarily to provide a simpleand eflicient instrument that shall be capable of registering thepaperboth longitudinally and laterally, and, secondarily, to adapt saidinstrument to be used on a paper-folding machine in which thepaper-delivering tapes are disposed parallel with the folding-rolls; andto that end the invention consists in the novel construction,combination, and arrangement of the mechanism for operating thepaper-registering instrument and auxiliary devices connected therewith,as hereinafter described, and set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation of apaper-folding machine equipped with my improved paper-registerin gdevices. Fig. 2 is a plan view of the same. Fig. 3 is an enlargedvertical transverse section on line Y Y in Fig. 2, showing theregistering instrument in position to allow the paper to be deliveredunder it. Fig. t is a further enlarged vertical transverse section ofthe registering instrument proper in position to register the paper,taken on line X X in Fig. 2. Fig. 5 is afront view of the same. Figs. 6and '7 are transverse sections on lines V V and Z Z, respectively, inFig. 5. Fig. 8 is a still further enlarged end elevation of themechanisms for imparting motion to the registering instrument, and Fig.9 is a transverse section of the longitudinally-movable bar whichcarries the registering instrument and means for transmitting motion tosaid bar.

Similar letters and figures of reference indicate corresponding parts.

A represents the main supporting-frame of a paper-folding machinecomprising the folding-rolls B B, the blade 0, which tucks the paper tobe folded into the bite of said rolls, the tapes a a, which deliver thepaper into said machine, and the front stop D, which arrests the advancemovement of the paper preparatory to its introduction into thefolding-rolls. V I

In the machine here presented the paperdelivering tapes a ct aredisposed parallel with the folding-rolls B B and receive longi: tudinal.movement from the usual feed-roll E E, from which they travel tosuitable rollers a 0; on the opposite side of the machine.

F F are the usual drop-rollers, which are over the feed-roll E, to pressthe sheet into intimate contact with the feed-roll and cause the same toforce the sheet onto the tapes a a, by which the sheet is carried alonguntil arrested by contact with 'the front stop D.

In the subsequent operation of the blade 0 introducing the sheet betweenthe folding; rolls B B said sheet is drawn transversely from the tops ofthe tapes a Before this introduction of the paper into the bite of thefolding-rolls B B the sheet is required to be registered or adjusted tobring the required line of folding of the sheet in coincidence with thebite of the folding-rolls. To accomplish this in an efficient andaccurate manner, I resort to the following construction, combination,and arrangement of parts, to wit:

Transversely over the tapes OtCt is disposed a longitudinallymovable barG, sliding in suitable guides G G on the frame A. By mechanismshereinafter described said bar receives intermittin g reciprocatingmotion. At opposite sides of the folding-rolls B B, I connect to the barG brackets composed of shoes I) Z), receiving said bar through them andhaving depending from them arms 19 17 which carry the registeringinstruments hereinaf ter described. Said shoes are adapted to be shiftedlengthwise of the bar and are clamped in their required positions bymeans of setscrews 17 19, passing through the shoes and engaging thebar. To permit the shoes to be accurately adjusted in their positions, Imount on the bar G hangers c c, which are likewise adapted to slidelengthwise of the bar and are clamped in position by means of set-screwsc. The lower end of each of said hangers is formed with a nut orscrew-threaded sleeve 0 through which passes the ad j usting-screw c,which is extended and passes through a nut 0 firmly attached to orintegral with the shoe 1), as more clearly shown in Fig. 5 of thedrawings. The said adj ustment of the bracket-shoe Z2 is effected byloosening the set-screws b b and c, and after the shoe 1) has beenplaced approximately in its required position'the setscrew 0' of thehanger c is tightened, so as to confine said hanger in its position.Then by turning the adjusting-screw 0 the shoe 1) is moved accurately toits required position and is then'fastened bytightening the set-screwsZ) 1;. The aforesaid adjustment is required to support the resigteriuginstrument in the path of the slit or perforation made in the paper forthe purpose of registering it thereby. A second adjustment is requiredof the two bracketarms b b at opposite sides of the foldingrolls toarrest the advance movement of the sheet in such a position as to causethe required line of folding of the sheet in coincidence with the lineof the bite of the foldingrolls. This adjustabilityisobtainedbytransverse guides d on the undersides of the shoes I) andcorrespondiugly-shaped heads (1'' on the upper ends of the bracketarmsZ1 Said bracket-arms are thus allowed to be shifted backward or forwardparallel with the tapes and support the registering instruments inproper positions to cause them to arrest the forward movement of thesheet precisely in a position to bring the line of folding of the sheetin coincidence with the line of the bite of the folding-rolls. To permitconvenient accurate adjustment of the said hanger-arms, I provide theheads (1 thereof with screwthreaded sockets e, parallel with the guides(I and engaged by the adjusting-screws e',which pass through rigid lipsc on the shoes Z) and are prevented from moving longitudinally bycollars 6 attached to the screws in front and rear of the said lips, asshown in Fig. 9 of the drawings. The hanger-arms b are each providedwith a vertical guide f, on which is a slide g, to which is pivotedvertically an arm h, preferably by means of a post it, fastened to orintegral with said arm and pivoted at its ends to the heads 9' g of theslide, as more readily seen by reference to Figs. 5, 6, and 7 of thedrawings. To the lower or free end of the arm 7b is fastened theregistering point or tongue 7L2, designed to enter into the slit orperforation in the paper to be registered. The: slide 9 receives therequisite intermitting vertical reciprocating motion by mechanismhereinafter described.

In a paper-folding machine having the delivering-tapes a a parallel withthe foldingrolls B B it is necessary to sustain the arms h hof theregisteringinstruments yieldingly toward the folding-rolls, so as toallow the paper to be withdrawn laterally out of engagement with theregistering-points 7L2 7L2 without tearing the sheet, and for thispurpose thesupporting-posts lb of the registering instruments arepivoted, as before described.

By means of stops t, secured to the slide g, and suitable springs i,holding the arms 7: in

contact with said stops, the registering in-' struments are heldnormally in position to engage the slits or perforations in the sheetpassing under said instruments.

To facilitate the entrance of the registering-point 7L2 into the slit orperforation in the sheet to be registered, a suitable sheet-depressor,preferably of the form of a suitablyshaped spring-plate j, is attachedto a supporting-bracket on the slide 9 to move vertically therewith.

The slide g receives intermitting reciprocating motion from a rock-shaftI, disposed transversely over the tapes a a and mounted in bearingsonbrackets II II, secured to the frame A. Said rock-sha ft has extendingfrom it arms I, the free ends of which are connected to the slides g bymeans of pitmen J. Said arms can be shifted lengthwise of the shaft toconform to the position of the brackets, which carry thehereinbefore-described registering instruments. By means of setscrews7;, connected to the arms I and engaging the rock-shaft, said arms areretained in their adjusted positions. The rock-shaft is oscillated bymeans of a rotary cam K, on which rides a roller Z, pivotedto one of thearms of a bell-crank lever L, pivoted to a hanger Z on the frame A. Tothe other arm of the said bell-crank is connected an upwardly-extendingrod L, which is guided vertically by means of a pin on, projecting froma stationary bracket m and passing through a vertical slot m in saidrod. The upper end of the rod L is provided with a rigidlaterally-projecting bifurcated head L the two prongs of which haveprojecting from opposing faces thereof tappets n and n, bearing,respectively, onto the top and bottom of a tongue 0, which projectsradially from a collar o, fastened to the rock-shaft I, as shown moreclearly in Fig. 8 of the drawings. The tappet n, which is subjected tothe strain of lifting the slides g, with the registering instrument, bythe arms I, attached to the rockshaft I, is made adjustable tocompensate'for the wear of the points of contact of said tappet andtongue 0. For this purpose the tappet passes loosely through the prongof the head L and rests with its lower end upon the to of a set-screw o"inserted in a ro'ection,

c on the rod L.

One of the chief objects of my present invention is to register thepaper laterally by the same instrument which registers said paperlongitudinally. For this purpose I employ the longitudinally-movablo barG, hereinbefore described, which bar receivesproperly-timedintermittingreciprocatingmotion preferably from therock-shaft I, which is movable longitudinally and reciprocated bysuitable actuating mechanism. To transmit said 'motion to the bar G, oneof the bracket-shoes b has rigidly projecting from it a finger p, whichis maintained in engagement with a circumferential groove 1) in theattaching-collar of the. arm I, as shown in Fig. 9 of the drawings. Forimparting the required reciprocating motion to the shaft I, I prefer toemploy a cam N, fastened to the shaft N, to which the cam K is attached.Upon the cam N rides a roller '2", pivoted to the free end of an arm 0,which is attached to the shaft q, mounted in bearings q q, secured tothe frame A. A lever 0, attached to the shaft q, extends upwardtherefrom and is connected to the outer end of a rod 0", the inner endofwhich is pivotally connected to ahub projecting from a sleeve 1*,mounted on the shaft I and held in place by means of collars r adjustably secured to the shaft at opposite ends of the sleeve.

To maintain the tappets n and n in contact with the tongue 0 during thereciprocating motion of the shaft 1, said tongue is elongated ordistended in the direction'lengthwise of the shaft and is preferablyprovided with grooves or ways for the tappets.

In connection with the described registering instruments I employ thealternately ad vancing and receding gage or front stop D, similar tothat shown in my Letters Patent No. 561,937, dated June 9, 1896. Saidfront stop rides upon bars 2 2, disposed at right angles to said frontstop and supported at their inner ends upon rollers 3 3, pivoted tosuitable stationary supports. The outer end of each of said bars hasrigidly secured to it a bracket 4, in which is journaled a rod 5, havingits inner end screw-threaded and passing through a nut 6, attached tothe front stop D. By the turning of the two screwrods the said frontstop is adjusted for different-sized paper to be registered and folded.

To turn the two screw-rods synchronously, I attach to each of themaworm-gear 7, which meshes with a corresponding gear 8, attached to ashaft 9, mounted in arms 10, formed on the brackets 4. A suitable crankor hand wheel 11 is attached to the end of said shaft for turning it.The outer end of each of the bars 2 2 is supported by an arm 12, fixedin a suspended position to a rock-shaft 13 and pivotally connected atits lower end to the bracket 2, as shown more particularly in Fig. 3 ofthe drawings. The rock-shaft 13 is actuated by a lever 14, fastenedthereto andhaving 011 its free end rollers 15, engaging a rotary cam 16,which imparts oscillatory motion to said lever.

To facilitate the second advance movement of the paper during thereceding of the front stop from its papenarresting position, I attach tosaid front stop suitable sheet-depressing devices, preferably of theform of springplates 3, attached to the free ends of arms '5, clampedonto the front stop and extending toward the registering instru men ts.The tension of the spring-plate may be made adjustable by a set-screw a,connected to the arm 11 and bearing upon the top of the spring-plate.Said sheet-depressing devices serve to increase the frictional hold ofthe tapes a a on the overlying sheet.

In the operation of the machine the registering instruments are held inelevated position to allow the incoming sheet to pass under them, and atthe same time the front stop D is in its rearmost position to arrest theadvance movement of the sheet before the slitted portions thereof arecarried directly under the registering.instruments. Then saidinstruments descend and the front stop D is drawn forward, which lattercauses the'sheet to receive a secondary advance movement, and in thismovement the registering-points 72, enter into the slits in the sheet,and thereby register said sheet longitudinally. As soon as this iseffected the longitudinallymovable bar G receives a reciprocatingmotion, and thereby causes the paper to be shifted laterally andregistered in said direction by the entered registering-point 77. on thearm h, which is sustained by the stop 1'. The sheet .thus registered isthen introduced into the bite of the folding-rolls B B, and in thisoperation the supporting-arms h of the registering-points k yield to thedraft of the sheet and allows the same to be drawn out of engagementwith the registeringpoints without danger of tearing the sheet.

What I claim as my invention is- 1. A combined longitudinally andlaterally paper registering instrument provided with means for engaginga slit or perforation in the paper, and actuated to effect saidengagement and thereby impart the first register to the paper, and tosubsequently move laterally while engaged with the paper,and therebyshift the paper to its second register as set forth.
